Noctilux
The Noctilux is an optical fiber microphone specifically designed to operate in MRI (Magnetic Resonance Imaging) environments. Thanks to its completely metal‑free design, it is immune to electromagnetic interference (EMI/RFI), thus ensuring reliable, undisturbed acoustic measurement.
Main Features
Bandwidth: 15 Hz to 15 kHz (±3 dB)
Signal-to-noise ratio: 70 dB (at 1 kHz, 94 dB SPL)
Sensitivity: 100 mV/Pa
Output: 3.5 mm jack
Fiber connector: FC/APC or E2000
Fiber bend radius: 5 mm (instantaneous), 40 mm (storage)
Operating temperature: -15 °C to +80 °C
Maximum sound pressure: 130 dB SPL
Power supply: 5 V DC via mains adapter (150 mA, 0.8 W)
Probe weight: only 2 g
Fiber compatibility: bare fiber (250 µm), loose tube (900 µm), 2–3 mm cable
Cable options: shielded, metallic, non-metallic
Use cases
MRI / Hospitals: acoustic measurement in environments sensitive to electromagnetic interference.
Industrial monitoring: in areas requiring a non‑metallic sensor.
Acoustic R&D: interference‑free testing in shielded environments.
System integration: ideal for applications with sealed feedthroughs or requiring long fibers (up to 10–20 km).
